The present invention relates to a container, and more particularly to a collapsible and disposable container for beverages or the like.

2. Description of Related Art

Tetra Pak packages is widely used containers for beverages or food. However, the Tetra Pak packages are difficult for recycling because a Tetra Pak package comprises multiple layers of aluminum films, papers and plastic films. In addition, a conventional Tetra Pak package has to be torn off before being folded for reducing spaces for recycling or reclaiming process. However, some parts of the conventional Tetra Pak package are bent and connected by glue or adhesive, to tear of the conventional package is difficult and time-consuming.

To overcome the shortcomings, the present invention tends to provide a container to mitigate or obviate the aforementioned problems.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT

With reference to FIGS. 1, 2, 7 and 8, a beverage container in accordance with the present invention comprises a body. The body is hollow is constructed by a front panel (30,30A), a rear panel (40,40A), a top panel (50,50A), two side panels (10,10A) and a bottom panel (20,20A).

The front panel (30,30A) has a top connected to one end of the top panel (50,50A), and the rear panel (40,40A) has a top connected to the other end of the top panel (50,50A). The top panel (50,50A) may be curved as shown. The side panels (10,10A) are mounted between the front, rear and the top panels (30,30A,40,40A,50,50A). The bottom panel (20,20A) is mounted between the front, rear and side panels (10,10A,30,30A,40,40A) to form a hollow body with a chamber for containing beverage, food or the like.

With further reference to FIGS. 3 and 4, the front, rear and top panels (30,30A,40,40A,50,50A) may be made of hard plastic material and each has a thickness larger than that of each one of the side and bottom panels (10,10A,20,20A).

The top panel (50,50A) has a top folding groove (51,51A) defined in the top panel (50,50A) along a direction perpendicular to the side panels (10,10A). In a preferred embodiment, the top folding groove (51,51A) is defined in the top of the top panel (50,50A). In an alternative embodiment, the top folding groove (51,51A) can be defined in the bottom of the top panel (50,50A).

The top panel (50,50A) has an opening defined through the top panel (50,50A) and communicating with the chamber. The opening is provided with a cap (65,80) to close the opening. With reference to FIG. 5, the opening is defined through the top of the top panel (50,50A) and may be defined at a position lower than a topmost position of the curved top panel (50). In a second embodiment as shown in FIGS. 7 and 8, the opening is defined the topmost position of the curved top panel (50A).

In the first embodiment, with reference to FIG. 5, a nozzle (60) is attached to the top panel (50) to close the opening in the top panel (50) and is provided with the cap (65). The nozzle (60) communicates with the chamber in the body and has an outer thread (62) formed around a free end of the nozzle (60). The cap (65) is attached to the nozzle (60) and has an inner thread screwed with the outer thread (62) on the free end of the nozzle (60). The nozzle (60) may be extendable to a position where the free end of the nozzle (60) is higher than the topmost position of the curved top panel (50). Consequently, the chamber of the body can be filled with beverage as full as possible to improve the use of the container.

In the second embodiment, the cap (80) is attached directly to the opening in the top panel (50A) to close the opening.

The bottom panel (20,20A) may be implemented by two plastic films connected with each other and has a bottom reinforced rib (75,75A). The bottom reinforced rib (75,75A) is embedded between the plastic films of the bottom panel (20,20A) and is X-shaped.

The bottom reinforced rib (75,75A) has a bottom folding groove (751) defined in the bottom reinforced rib (75,75A) and parallel with the top folding groove (51,51A) in the top panel (50,50A). In a preferred embodiment, the bottom folding groove (751) is defined in a top of the bottom reinforced rib (75,75A) on the bottom panel (20,20A). Alternatively, the bottom folding groove (751) may be defined in a top of the bottom reinforced rib (75,75A) on the bottom panel (50,50A). In addition, the bottom folding groove (751) is in alignment with the top folding groove (51,51A) and is located at a surface that is perpendicular to the side panels (10,10A) and is parallel with the front and rear panels (30,30A,40,40A).

With reference to FIG. 1 to 3, each side panel (10,10A) is implemented by two plastic films connected with each other and may further have a side reinforced rib (70). The side reinforced rib (70) of each side panel (10) is embedded in the plastic films of the side panel (10), is X-shaped and has a side folding groove (71) defined along a direction parallel with the front panel (30). In a preferable embodiment, the side folding grooves (71) in the side panels (10) are located at the surface at which the top and bottom folding grooves (51,751) are located.

With the reinforced ribs (70,75) on the side and bottom panels (10,20,20A), the structural strength of the side and bottom panels (10,20,20A) implemented by plastic films can be reinforced. Thus, the volume of beverage that the container can hold can be increased. In addition, for small volume usage, the side reinforced ribs (70) can be kept free from the side panels (10A) as the container shown in FIGS. 7 and 8.

To fold the container, with reference to FIGS. 1, 2 and 6, the top, side and bottom panels (10,10A,20,20A,30,30A) can be folded with the folding grooves (51,51A,71,751). Because the thickness of the side and bottom panels (10,10A,20,20A) are smaller than that of the front, top and rear panels (30,30A,40,40A,50,50A), the container can be easily collapsed to reduce the space for recycling or reclaiming the container. Furthermore, because the panels (10,10A,20,20A,30,30A,40,40A,50,50A) are formed by plastic material, the container is sorted to plastic for a recycling or reclaiming process. To recycle or reclaim the container in accordance with the present invention is easy and convenient.
